The forces and moments induced by the vicinity of banks on a sailing vessel are known as bank effects.
An extensive set of model tests have been carried out in a towing tank to investigate bank effects induced
by irregular bank geometries. Tests along sloped surface-piercing as well as submerged banks are carried
out. A mathematical model (for the longitudinal force, sway force, yaw moment and sinkage) found on
these tests is formulated. This model copes with the geometry of the banks tested and not tested bank
geometries. This paper emphasises on the mathematical model and on two parameters of this
mathematical model: The distance between ship and bank d2b and the equivalent blockage meq such that the properties of an irregular bank geometry are taken into account.
